Does expanding foam lift concrete?

• <div><p>Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer <a href="https://www.angi.com/articles/mudjacking-vs-polyjacking.htm">polyjacking over mudjacking</a> for more damaged and delicate slabs.</p></div>

Q: What’s the most affordable way to level a concrete floor?

The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.</p></div>

Q: How long does it take for mudjacking to dry or cure?

• <div><p>Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.</p></div>

Although the company is a nation wide chain, its a franchise and a small business. He is an honest Vermonter with Vermont values which I appreciate. He gave me options but didn't try to talk me into something I couldn't afford and is doing the work within two weeks which I was also happy about being a very busy time for this type of thing."

Concrete Mudjacking questions, answered by experts

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.

Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture.
